Adjusting inflation pressure is a feature. I run my tires higher than the vehicle recommendation but still below the sidewall limit for improved fuel economy. Airing down for sand is a thing too.
I worked in a tire shop, and chronic overinflation caused tires to go bald in the center of the tread while the sides had tread left. Have to replace them more often then.
I just got a set of tires replaced under tread life warranty because they wore out edge first. The tire shop set the pressure higher than recommended and actually a little higher than I usually set it myself.
